A curve of the tractor automatic mechanism transmission (AMT) dynamic power shifting schedule was presented by conducting an experiment. Taking the degree of jerk during shifting as the primary control parameter of the shifting quality, the AMT control system was developed based on the electric hydraulic servo system. By analyzing the experience of a skilled driver, a fuzzy controller was designed, and the control algorithm of the tractor AMT dynamic power shifting schedule was established. The experiment results show that the faster the shifting is, the bigger the jerk is. The biggest jerk was 4.76m/s3 that happened at the clutch’s lock-up time, all of the jerk’s values were smaller than 17.64m/s3, which was the biggest jerk that people can endure. The results indicate that the fuzzy control method is feasible for the tractor AMT control, and can improve the quality of the tractor AMT shifting. 
